The molarity of the hydrogen peroxide solution from the information supplied in the question is 12.26 M.

Co = 10pd/M

Where;

Co = concentration = ?

p = percent of the hydrogen peroxide = 30%

d = Density of hydrogen peroxide = 1.39 g/ml

M = Molar mass = 34 g/mol

Substituting values;

Co = 10 × 30 × 1.39/34

Co = 12.26 M

The molarity of the hydrogen peroxide solution from the information supplied in the question is 12.26 M.
